IMPROVEMENT lN PLOUGHS.

TO ALL WHOM IT MAY CONCERN'.

Be it known that I, S. J. LEACII, of Tuscaloosa, in the county ofTuscaloosa, and State of Alabama, have invented n. new and usefulImprovement inIPloughs'; and I do hereby declare that 'the following isa full, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part ofthis speciiication, in which-'Figure` 1 is an outsideview of the mould-board of my improved plough.

Figure 2 is an inside view of the samc.

Figure 3 is a detail sectional view of the same, taken through the linea: x, g. 2.

Similar letters of reference indicate .corresponding parts. i

My invention has for its object to furnish an improved plough, providedwith a detachable facing forme'd of wood or other material, to whichadhesive soils (will not adhere and clog the plough, ywhich shall becheap,

more durable, and more e'ective than the pleughs ordinarily used in suchsoils; and it consists in facing the' mould-board of theplough withathindetachable sheet or plate of wood, steel, or other suitab''ematerial, and in forming the mould-board of the plough with a shoulderand slots or socketsto receive the forward edge and tongues of thefacing-plate; the'whole being constructed and arranged as hereinaftermore fully described,

A is the standard, and B is the mould-board ofthe plough, which may becast in one piece in the ordinary manner. The'mould-board B is formedwith a shoulder, b', formed upon it at the point at which they forwardend of the facing-plate should end. The shoulder li should project sofar as to equal the thickness of the facing-plate, and should projectrearward, so as to form an acute angle withthe mould-board B'. vC aretwo or more slots or sockets formed in the mould-board B, fer thereception of tongues formed upon the forward end ofthe facing-plate. Dis the facing-plate, which is made of a thin sheet or plate of wood,steel, or other suhstance, to which the soil in which thelpleugh is tobe used will not adhere.- When the plate D is made of wood, the thinboard of which it is formed is steamed and bent or pressed vintotheexact forin of the mould-beard of the plough; and when made of steel, itis swnged into proper shape. The forward edge of the facing-pleite D isso formed as to fit into the inclined or grooved shoulder 6 ofthemould-'board B, and upon it are formeditwo or moretongues, d', fittinginto the slots or sockets C, formed in the mould-board B for theirreception, as herein- .Y

before described, so as to render the connection between thefacing-plate and mould-board rmer, closer, and more secure than itotherwise would be. The facing-plate D may be secured to the mould-boardby screws or bolts 4passing through the said facing-plate and saidmould-board, so as to hold all parts of the facing-plate close uplagainst the mould-board. y

By this construction the cast-iron. mould-board oi' the plough supportsthe facing-plate D, and keeps it in proper-form, and at the same timeenables the said facing-plate to beremoved or attached easily, quickly,and conveniently, whenever desired. h

I claim as new, and desire lto secure by Letters Patent- 1. 'Facing themould-hoard cfa plough with a thin detachable sheet or plate of wood,steel, er other snitable material, substantially as herein shownanddescribed, and for-the purpose set forth. v

2.v Forming the mould-board B oi' a plough with a. shoulder, ,-and withslots or sockets C, to receive the forward edge and tongues of thefacing-plate D, substantially as herein shown and described, and for thepurpose set forth.
